Antipernicious Anemia Factor Guide

The journey to a cure began with George Whipple , who was studying blood regeneration in anemic dogs. Due to a happy laboratory accident where a technician fed the dogs raw liver instead of cooked food, Whipple realized that .

Hearing of this, Boston physicians George Minot and William Murphy decided to try feeding raw liver to human patients dying of pernicious anemia. To everyone's astonishment, patients forced to consume about a half-pound of raw liver daily made complete recoveries. Whipple, Minot, and Murphy shared the for this discovery. 2.
